Surface Quality after High-Speed Grinding

Resumo

In producing machine parts from the hard materials used today in the military–industrial complex, attainment of the required precision is difficult and sometimes unfeasible unless finishing operations are employed. In general, finishing operations are expensive and slow and they require highly skilled workers and specialized equipment. That considerably increases the production costs. Finishing operations can only be eliminated if the cutters used in the prior machining processes ensure satisfactory surface quality. However, that is not always the case, on account of bluntness of the tool. In the present work, attention focuses on the precision that may be attained in machining key components made of hard materials when using high-quality hard-alloy cutters produced by ultrahigh-speed grinding.
